“…garcae and P. syringae pv. tabaci, based on the symptoms described by Zambolim (2015), using a grading scale from 1 to 5 (Sera et al, 2017), in which: grade 1 = absence of necrotic lesions; 2 = from 0.01 to 3% leaves with small necrotic lesions (up to 0.5 cm), yellowish halo hardly visible to the naked eye; 3 = 3.01 to 15% leaves with small and medium lesions (up to 1 cm), with yellowish halo visible to the naked eye, with the possibility of 1% of large lesions (more than 1 cm); 4 = 15.01 to 30% leaves with small to large lesions; 5 = more than 30% of the leaves with small to large lesions, with the possibility of dieback of the branches. In this assessment, we assessed the leaves from the bottom third to the upper third of the plant, considering the first pair of fully expanded leaves to the tenth pair of fully expanded leaves.…”

“…Results obtained in field trials with natural occurrence of BHB showed that C. arabica cv. IPR 102 had a high level of resistance (Ito et al, 2008;Sera et al, 2017), while IPR 103, IPR 104, IPR 108 and IAPAR 59 showed an intermediate level of resistance (Ito et al, 2008). There are no studies reporting resistance to BLS in coffee.…”

The aims of this study were: (a) to evaluate the resistance of coffee cultivars to Pseudomonas syringae (PS); (b) verify if there are coffee genotypes that present less wounds on the leaves; (c) to study the correlation between amount of wounds and PS severity. The field trial was installed in April 2014 at the IAPAR’s experimental station (Londrina, Paraná, Brazil). 18 Arabica coffee cultivars were evaluated. The cultivars Mundo Novo IAC 376-4 and Catuaí Vermelho IAC 81 were the susceptible controls and IPR 102 was the resistant control. After 32 months of planting the field trial, resistance to PS was evaluated in December 2016. The evaluation of the PS severity was carried out under conditions of natural infections of P. syringae pv. garcae and P. syringae pv. tabaci based on the symptoms, using a grading scale from 1 to 5. The number of wounds on the leaves of the eight cultivars were counted. The results showed that IPR 102 was resistant to Pseudomonas syringae, whereas IPR 99, Arara, IPR 107, Acauã, Sabiá, Catucaiam 24137, Japy and Catuaí Vermelho IAC 81 were susceptible. Mundo Novo and Catucaí Amarelo 2SL were more susceptible than Catuaí Vermelho. IPR 106, Japiam, Catiguá MG 2, Catiguá MG 1 and IBC Palma 2 showed moderate resistance, while IPR 103 and Catucaiam 2015479 were moderately susceptible. The cultivars IPR 102 and IPR 106 presented resistance to wounding because they had lower wounds than other cultivars. Increased leaf wounds was associated with increased P. syringae severity.

“…In Brazil, all arabica cultivars registered by the Brazilian Ministry of Agriculture, Livestock and Food Supply (Ministério da Agricultura, Pecuária e Abastecimento -MAPA) are BHBsusceptible, except for cultivar IPR 102, which is resistant to the disease (SERA et al, 2017).…”

Multiple resistance to bacterial halo blight and bacterial leaf spot in Coffea spp.*

Breeding for genetic resistance is an important method of crop disease management, due to the numerous benefits and low cost of establishment. In this study, progenies of 11 Coffea species and 16 wild C. arabica accessions were tested for their response to Pseudomonas syringae pv. garcae, the causal agent of bacterial halo blight, a widespread disease in the main coffee-producing regions of Brazil and considered a limiting factor for cultivation in pathogen-favorable areas; and also to P. syringae pv. tabaci, causal agent of bacterial leaf spot, a highly aggressive disease recently detected in Brazil. Separate experiments for each disease were carried out in a greenhouse, with artificial pathogen inoculations and ideal moisture conditions for disease development. The results showed that C. canephora, C. congensis, C. eugenioides, C. stenophylla, and C. salvatrix progenies, the wild C. arabica accessions Dilla & Alghe and Palido Viridis, and cultivar IPR 102 contain satisfactory levels of simultaneous resistance against bacterial halo blight and bacterial leaf spot. These results are useful in breeding programs for durable resistance to multiple biotic agents, providing new combinations of resistance alleles by hybridization, as well as for phytopathological studies, to identify infraspecific variability of the pathogens.

“…Among the coffee ( Coffea arabica L.) cultivars planted in Brazil, the Mundo Novo 376/4 cultivar corresponds to almost half of the planted area. This cultivar is susceptible to main coffee diseases, including BHB [ 21 , 22 ]. The Iapar-59 cultivar has an intermediate level of resistance to BHB [ 23 , 24 ] and is resistant to coffee leaf rust ( Hemileia vastatrix ) [ 23 , 25 ].…”

Coffee production is one of the main agricultural activities in Brazil, and several coffee cultivars with disease resistance have already been developed. The secondary metabolites produced by plants are closely associated with defense strategies, and the resistance of coffee cultivars to bacterial halo blight (BHB) can be related to these compounds. Therefore, this study aims to compare a partially resistant coffee cultivar (Iapar-59) and a susceptible cultivar (Mundo Novo 376/4) to BHB (Pseudomonas syringae pv. garcae) in relation to the chemical composition and antioxidant activity of the leaf extracts. In addition, this study determined the total phenolic and flavonoid contents and phenolic profiles of the Iapar-59 leaf extracts of plants inoculated with P. syringae pv. garcae. The Iapar-59 extract showed a higher content of phenolic compounds and flavonoids than the Mundo Novo 376/4 extract. Both cultivars contained gallic, chlorogenic and caffeic acids; however, the highest contents were quantified in the Iapar-59 cultivar. The leaf extracts from the Iapar-59 cultivar exhibited higher antioxidant activity. Higher concentrations of gallic, caffeic and chlorogenic acids and the presence of vanillin were detected in the extract of cultivar Iapar-59 inoculated with P. syringae pv. garcae.
